    Abstract: A lens element intended to be worn in front of an eye of a wearer comprising: -a prescription portion configured to provide to the wearer in standard wearing conditions a first optical function based on the prescription of the wearer for correcting an abnormal refraction of said eye of the wearer, and -a plurality of contiguous optical elements, wherein each optical element has a simultaneously bifocal optical function that provides simultaneously: -a second optical function in standard wearing conditions and -a third optical function of not focusing an image on the retina of the eye in said standard wearing conditions so as to slow down the progression of the abnormal refraction of the eye.

    Abstract: The invention relates to a method for determining a progressive ophthalmic lens, comprising: - determining a first intermediate value of regression (d1) as the strongest regression that can be applied on the front surface of the lens while keeping a mean sphere value in at least a portion of the lower part of the rear surface of the lens less or equal to a first predetermined value (V1); - determining a second intermediate value of regression (d2) as the strongest regression that can be applied on the front surface of the lens while keeping a mean sphere value in at least a portion of the lower part of the front surface of the lens superior or equal to a second predetermined value (V2); - determining a third intermediate value of regression (d3) as the strongest regression that can be applied on the front surface of the lens while keeping an addition on the rear surface of the lens less or equal to a third predetermined value (V3); - determining a value of regression (d) for the front surface as the maximum value among the first, second and third intermediate values of regression.
